Thanks... . First let me say I made a mistake, the front valving is 170/60, I am sorry.
Sunday my wife and I took a long highway drive, and we both agreed that the changes we made were very much positive, and worth the investment. The front seems to be very,very close to being perfect. Now I have no way of noing what aliitle more or less valving would do, but it feels right. Now when the suspension needs to travel, it does so with out a thud or hard hit. The suspension just moves the amount it has to, and it does so smoothly and with out incident. Nothing harsh, just smooth travel, with control. The back is valved at 255/70 and it feels good, but I am still playing with air pressure, it does not need as much as in the past. Right now I am at 20psi, where I use to run 50-55psi. The overall ride is much improved, and feels like such a different truck. I also got rid of the drone with the Aero Turbine muffler. We were experimenting and the rode was fairly clear, so we ran about 30 mile at 80-105 mph and the control at those speeds were fantastic. There were several large dips in the highway that like to unload the suspension at a very fast rate, giving that feeling on the road dropping out from under you, making your stomach feel like it is in your throat. This was handled extremely well, the suspension dropped off, but not the normal sudden way, just controlled, and the rebound as control. Totally different, but a very welcome change. So far there is nothing I would have done differently. If I would not use my truck for towing, I would have went with the Dick Cepeek long travel kit. I think that along with this set-up would be simply awesome. This was the first time I really had a chance to push my truck, since it's new fuel plate and AFC adjustment, they worked very well also, and the extra power is well noted. There is some extra smoke as well, but it is not excessive.
